a Pixel Editor, have i got one ?

Hi i have a PNG file that i want to use on my Rapidweaver website, it is a fairly basic social Icon that i found via Google, i have now got it on my Web site, but the corners have three white pixels each corner and it looks awful on top of the background i have.

I need a pretty basic Pixel Editor to delete these white pixels.

I have previewed the picture in Preview and iPhoto but i dont see that i can edit single pixels with these two bog standard Apps, what should i be using please ?.

Ah, i thought i had cracked it, i found an OnLine editor called PixelMator with which, after a struggle i could change the colour of the Pixels on the corners, MY MISTAKE, i NEED to make the corners transparent, changing the colour wasnt the answer.

1. Open the item in Pixelmator.
2. Using the magic wand tool, click on one of the white pixels, and while still holding the mouse button down drag out to select the other white pixels.
3. Press delete to delete the selected white pixels.
